Great experience
I had a great experience using getyourpet.com. It's a bit scary having to give up your dog for adoption because you don't know what people have in mind for your beloved dog. This site allowed me to talk with potential adopters. Then when I felt good about one of them, we set up a meet-up through the site. All went well and I still get updates on my dog through the site from his new owner. The site allows you to send messages only to the adopter once the adoption is official.
